The past literature suggests the hypothesis that depression is associated with decreased physical functional ability in stroke patients. On a medical rehabilitation ward, 21 stroke patients were evaluated for depression by psychiatric interview and self-report, and were also rated on the Barthel's Functional Index (BFI). The hypothesis was supported: Patients scoring 17 or higher on the Beck Depression Inventory (BDI) (N = 7) had lower initial scores on the BFI than patients with lower BDI scores. There was a trend for these seven depressed patients to improve more slowly as ascertained by the BFI. Depression was suggested to lower functional ability by increasing fatigue, hopelessness, and decreasing motivation.
